Replace console statements with structured logger calls

- Replace 30 console.log/error/warn statements with appropriate logger calls
- Add logger imports where missing (PlatformServiceFactory, PlatformServiceMixin)
- Maintain eslint-disable comments for critical error logging in worker context
- Improve error handling consistency across platform services
- Clean up commented-out logger statements in WebPlatformService

Files affected:
- src/db/databaseUtil.ts: 4 console statements → logger calls
- src/main.electron.ts: 3 console statements → logger calls
- src/registerSQLWorker.js: 9 console statements → logger calls
- src/services/PlatformServiceFactory.ts: 1 console statement → logger call
- src/services/platforms/WebPlatformService.ts: 8 console statements → logger calls
- src/utils/PlatformServiceMixin.ts: 5 console statements → logger calls

Reduces ESLint warnings from 111 to 82 (eliminates all no-console warnings)
